SPENCER E. PERLES, OF ltlINNEAEOLIS, ID/IINNESOTA, ASSEGNOR, BY MESNE ASSIGN- IENT, T() BEEll/AI TRACTOR CMPANY, OF MINNEAPOLIS, IVINNESOTA, A COR- BORATIGN OF BINNESOTA.

- miniemen WHEEL.

To all fio/0m it may concern Be it linown that l, Srnrtcnr. Prrnnrs, a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and `use il Improvements in Traction li'fheels, o which the following is a specilioation.

My invention relates to devices tor increasing the width ot tread et a traction 'theel and particularly to a means tor securing the extension of the tread to the wheel rim.

A i'urtiier object is to provide a clamping means for the extension which will hold. it 'igid while in use and can be easily and quickly mounted on the wheel.

The invention consists generally in various constructions and combinations, all as hereinaiter described and particularly pointed out in the claims.

ln the accompanying drawings forming part or this specilication,

Figure l is a side elevation of a traction wheel with my invention applied thereto,

`Figure 2 is a plan view, showing a portion orp the rim in section,

Figure 3 is an edge view ot the clamp bar,

Figure 4t is a top view. i

ln the drawing, 2 represents'the rim of a traction wheel, having a hub 3 and spokes -l radiating therefrom. 5 represents a series ot traction cleats provided with lflanges G having holes 7 through. which bolts 8 pass to secure the cleats to an auxiliary rim 9, o-ne edge ot which is adapted to lit the rim 2 and form a lateral continuation of the tread surface ot the rim. The cleats 5 extend beyond one edge ot the auxiliary rim 9 and lap the tread surface oit the rim 2 and bear thereon` without being secured`r said cleats being obliquelj,Y or diagonally au ranged.` as shown in Figru'e 2. llhe main wheel rim 2 has an `internal annular flange l0 and 'for securing the rims together l profide a series oi' bars 1l having hooks 12 at one end to engage the ring l0, and similar hooks 13 at the opposite end to engage the outer edge of the auxiliary rim 9 and eX- tending in a straight line between said outer edge and the flange 10, leaving a gap or space between the bar and the inner surfaces oi the rims. prefer to arrange these bars so that the bolts S may tit within holes 13 therein and when the nuts are tightened, these bars will be bent slightly and drawn toward the inner faces ot' the rims and put under tension sutliciently to draw the rim 9 snugly against the rim 2 and clamp them Securely together, thereby making practically' one rim of the two and providing substantially a traction surface of double width of the rim 2. lWhenever desired, these bolts may be loosened and clamping bars ll released and the auxiliary rim detached from the main rim.

,l prefer to divide the rim 9 transversely and secure the ends together by means oi bolts 14 passing through the inwardly turned ends of the rim. rlhis construction may, however, be modilied in various ways. Any suitable number of the clamps ll mav be employed. i

l claim as my invention:

l. The combination, with a tractor wheel and rim, ot a supplemental rim of substantially the same diameter adapted to lit against one edge of the main rim, bars disN posed at intervals around the periphery of said main rim and having means engaging said main and supplementary rims for hold'- ing them together, and said bars having meansy for flexing them to clamp together the abutting surtaces ot said rims.

Q. rlhe combination, with a traction wheel and rim, of a supplementary rim ot suhs'tantially the same diameter and adapted to lit against the main rim and means enga@- ing said main rim and said supplementary rim for locking them together, and a series of traction cleats secured only to said sul plementary rim and extending over the surtace et said main rim.

3. The combination, with a traction wheel having a rim and an .internal ll:-;.n ;'cy ot' a supplementary rim litting the edge ot said traction wheel rim, bars l :wing hooks termed on the ends thereof for engaging the flange of said wheel rim and said nipple-- mentary rim, and bolts passing through said bars and said supplementary rim tor putd ting said bars under tension and drawing;` the abutting edges of said rims together.

4. The combination, with a traction wheel, oit a supplementary rim seated against one edge of the wheel rim and forming a traction extension thereof, bars having means at one end in engagement with said supplementary rim and et the other end in engagement With the main Wheel rim, and means for flexing said bars to draw said main and supplementary rims together.

5. The combination, with a traction wheel rim, of a supplementaryrm fitting one edge thereof, @series of cleats mounted on sind supplementary rim and having one end projecting across said main Wheel rim but unsecured thereto, and means for clamping said main and supplementary rims together.

6. The combination, with a traction wheel rim, of a supplementary rim fitting one edge thereof, a. series of cleats mounted on one rim and having one edge projecting across the other rim but unsecured thereto, and means for clamping said main and supplementary rims together.

In Witness whereof, I' have hereunto setmy hand this 16 day of May 1919.
